[0002] With the rapid development of social economy, transformers are used more and more. Distribution transformers are one of the important equipment in the power supply and distribution systems of industrial and mining enterprises and civil buildings. Among them, oil-immersed transformers refer to a transformer in which the main body of the transformer is immersed in an oil tank. Oil is used as the main insulation means of the transformer, and it is cooled by oil as a cooling medium. In addition, the oil in the oil tank can also protect the core and windings from the influence of moisture in the air. Therefore, oil-immersed transformers are currently a more popular type of transformer. Due to the excellent performance and low price of transformer oil, most power transformers still use transformer oil as an insulating and cooling medium.

[0016] Step 1: Oil circulation;

[0017] Step 2: Oil filtration;

[0018] Step 3: impurity separation;

[0019] Step 4: Filter vibration.

[0020] The present invention has the following beneficial effects:

[0021] When the piston rod moves to the upper part of the connecting part of the elbow and the round tube, the negative pressure can absorb the oil in the oil tank, and the oil enters the inside of the round tube, and the oil enters the inside of the elbow through the round tube. The oil enters the inside of the pumping pipe through the elbow, and the oil enters the inside of the discharge pipe through the pumping pipe, so that the oil enters the inside of the oil tank through the discharge pipe, so that the oil circulates to prevent the oil quality from deteriorating. When the piston rod moves upward, the piston rod drives the support frame to move upward, the support frame drives the vertical rod to move upward, the vertical rod drives the annular shell to move upward, and the annular shell drives the filter screen to move upward. During the process of the filter screen moving upward, the impurities in the oil in the oil tank are filtered, thereby improving the purity of the oil and the quality of the oil.

[0022] (2) In the present invention, the annular shell drives the lifting plate in the filter assembly to move upward along the inner wall of the oil tank. When the lifting plate moves to the top of the inner wall of the oil tank, it is subjected to the reaction force of the oil tank, so that the lifting plate moves closer to the annular shell. The lifting plate drives the first rotating bar to rotate, which is limited by the limiting rod. The first rotating bar drives the scraper plate to slide along the outer wall of the limiting rod. During the movement of the scraper plate, the impurities on the top of the filter screen are scraped off to prevent the impurities from clogging the filter holes of the filter screen, thereby improving the filtering effect of the filter screen on the oil. The scraper plate drives the sliding plate to slide along the outer wall of the limiting rod. The movable frame rod moves, and the sliding frame rod drives the special-shaped block to move, and the two special-shaped blocks approach each other. When the two special-shaped blocks come into contact, they are squeezed and the special-shaped block approaches the scraper plate. The special-shaped block drives the second rotating bar to rotate. Limited by the scraper plate, the second rotating bar drives the concave shell to slide laterally along the outer wall of the scraper plate, and the concave shell drives the auxiliary plate to move. During the movement of the auxiliary plate, the outer wall of the scraper plate is scraped to prevent impurities from adhering to the outer wall of the scraper plate and affecting the subsequent scraping effect of the scraper plate on the oil.

[0023] (3) According to the present invention, when the scraper plate moves, the scraper plate drives the rack to move, and the rack will contact the top of the gear during the movement, so that the gear rotates, and the gear drives the threaded rod to rotate. The second fixed rod is limited, and the threaded plate moves along the outer wall of the second fixed rod during the rotation of the threaded rod, and the threaded plate drives the telescopic plate to move, and the telescopic plate drives the elastic plate to move. During the movement of the telescopic plate and the elastic plate, the impurities scraped by the scraper plate are scraped off. When the telescopic plate is squeezed by the two scraper plates, it automatically shrinks, and when the elastic plate contacts the bottom end of the auxiliary plate during the movement, the elastic material of the elastic plate can prevent the elastic plate from getting stuck during movement. When the impurities are pushed to the side wall of the oil tank by the telescopic plate and the elastic plate, the extrusion block driven by the threaded plate will first contact the rotating plate, so that the impurities can enter the interior of the impurity storage shell, thereby separating the impurities in the oil from the oil, and preventing the impurities from entering the interior of the oil again.

[0024] (4) In the present invention, when the scraper plate moves, the bottom of the threaded plate will come into contact with the top of the conical slide rod, so that the conical slide rod is squeezed and the conical slide rod moves vertically downward, and the conical slide rod drives the connecting plate to move downward. When the threaded plate is no longer in contact with the conical slide rod, it is elastically deformed by the reset spring, and the reset spring drives the connecting plate to move upward. The connecting plate drives the impact plate to move upward. During the upward movement of the impact plate, it will come into contact with the bottom of the filter screen, and impact the bottom of the filter screen, so that the impurity particles in the filter holes of the filter screen are shaken off, thereby improving the filtering effect of the filter screen.

[0025] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

During the rotation of the threaded rod 575, the threaded plate 577 moves along the outer wall of the second fixed rod 576. The threaded plate 577 drives the telescopic plate 579 to move. The telescopic plate 579 drives the elastic plate 5711 to move. During the movement of the telescopic plate 579 and the elastic plate 5711, the impurities scraped by the scraper plate 557 are scraped away. When the telescopic plate 579 is squeezed by the two scraper plates 557 and automatically contracts, and the elastic plate 5711 contacts the bottom end of the auxiliary plate 566 during movement, the elastic material of the elastic plate 5711 can prevent the elastic plate 5711 from getting stuck. When impurities are pushed to the side wall of the oil tank 2 by the telescopic plate 579 and the elastic plate 5711, the extrusion block 5710 driven by the threaded plate 577 will first contact the rotating plate 5713, allowing the impurities to enter the interior of the impurity storage shell 5712, thereby separating the impurities in the oil from the oil and preventing the impurities from entering the interior of the oil again.

[0059] When the scraper plate 557 moves, the bottom of the threaded plate 577 will come into contact with the top of the conical slide bar 581, so that the conical slide bar 581 is squeezed, and the conical slide bar 581 moves vertically downward, and the conical slide bar 581 drives the connecting plate 583 to move downward. When the threaded plate 577 is no longer in contact with the conical slide bar 581, it is elastically deformed by the return spring 582, and the return spring 582 drives the connecting plate 583 to move upward, and the connecting plate 583 drives the impact plate 584 to move upward. During the upward movement of the impact plate 584, it will come into contact with the bottom of the filter screen 554, and impact the bottom of the filter screen 554, so that the impurity particles in the filter holes of the filter screen 554 are shaken off, thereby improving the filtering effect of the filter screen 554.
